Here's a reminder you need to clean your frames as well as your lenses! Just got this frame as part of a larger set and as I started to clean it nothing but chipped paint and dirt came off of it. This is the #1 reason M Frame lenses get scratched and marred inside the frame, and it pains me to see the lenses beat up so badly when all you need to do is clean out the frame. These lenses have the iridium worn right off. I have lenses that are several years old and got swapped a lot. They have frame scratches, sure, but they don't look like they've been sand blasted! All you need are some cotton swabs. Pull and pinch the end of the swab away from the core so it will reach into the frame's lens channel. Wet down the inside of the frame with cleaning spray, soap and water, etc. Run swabs in until they come out clean or close to it. One pass in my daily wear frame, a little crud: One of the frames I just got needed a few more: And this one STILL isn't clean after a LOT of scrubbing! No wonder the god damn lenses were getting beat to hell in this frame! CLEAN YOUR FRAMES!
